(1) This Part is not intended to limit or exclude the operation of another law of the Commonwealth (including other provisions of this Act) relating to:
(a) the search of premises; or
(b) the searching of persons or conveyances; or
(c) the seizure of things; or
(d) the requesting of information or documents from persons.
(2) To avoid any doubt, it is declared that even though another law of the Commonwealth (including other provisions of this Act) provides power to do one or more of the things referred to in subsection (1), a similar power conferred by this Part may be used despite the existence of the power under the other law.
